Codeigniter 3: sending account activation message fails

Question

I am working on a Register and Login application using CodeIgniter 3 and Twitter Bootstrap.

When a user registers , an email should be sent to the address that he provided using the link to confirm the account. The problem is that the confirmation email does not send .

In Usermodel , I have:

public function activationEmail($first_name='', $last_name='', $email='', $verification_key='')
{
    $this->load->library('email');
    $config = Array(
        'protocol' => 'smtp',
        'smtp_host' => 'smtp.code-love.tk',
        'smtp_port' => 465,
        'smtp_user' => '[e-mail]',
        'smtp_pass' => '******',
        'smtp_crypto' => 'ssl',
        'mailtype'  => 'html', 
        'charset'   => 'iso-8859-1'
    );

    $messg = 'Wellcome, '. $first_name . ' ' . $last_name . '! Click the <strong><a href="'.site_url('/signin/activateaccount/'. $verification_key).'">confirmation link</a></strong> to confirm your account.';


    $this->email->initialize($config); 
    $this->email->set_newline('\r\n');
    $this->email->from('mail.code-love.tk','Razvan Zamfir'); 
    $this->email->to($email);
    $this->email->subject('Account activation');
    $this->email->message($messg);
     if (!$this->email->send()) {
    show_error($this->email->print_debugger());
}
  else {
    echo 'Your e-mail has been sent!';
  }
}

In my registration controller , I have this code:

public function signup() {
    $this->form_validation->set_rules('first_name', 'First name', 'required');
    $this->form_validation->set_rules('last_name', 'Last name', 'required');
    $this->form_validation->set_rules('email', 'Email', 'required|trim|valid_email');
    $this->form_validation->set_rules('password', 'Password', 'required|min_length[6]');
    $this->form_validation->set_rules('cpassword', 'Confirm password', 'required|matches[password]');
    $this->form_validation->set_error_delimiters('<p class="error">', '</p>');

    if ($this->form_validation->run()) {
        $first_name = $this->input->post('first_name');
        $last_name = $this->input->post('last_name'); 
        $email =  $this->input->post('email');
        $password = $this->input->post('password');
        $verification_key = md5($email);
        $date_created = date('Y-m-d H:i:s');
        $date_updated = date('Y-m-d H:i:s');
        $active = 0;
        // Load user model
        $this->load->model('Usermodel');

        // If email does not already exist in the database 
        // signup new user
        if (!$this->Usermodel->email_exists($email)) {
            if ($this->Usermodel->user_register($first_name, $last_name, $email, $password, $verification_key, $date_created, $date_updated, $active) && $this->Usermodel->activationEmail($first_name, $last_name, $email, $verification_key)) {

                $this->session->set_flashdata("signup_success", "Your account has just bean created. You must confirm it before you can sign in. We have send you a confirmation email at $email for this purpose.");

            } else {
                // unless sigup does not fail for whatever reason
                $this->session->set_flashdata("signup_failure", "We ware unable to create your account.");
            }
            redirect('signup'); 
        } else {
            // If email is already in the database
            // urge user to sign in (redirect to signup page too)
            $this->session->set_flashdata("email_exists", "The email address $email already exists in the database. Please signin.");
            redirect('signin'); 
        }
    } else {
        $this->load->view('signup');
    }
}

Registration occurs with an error below, and an email with confirmation is not sent. I do not do this from the local XAMPP / WAMP / MAMP server, but from live, you can register .
